It might be a cliche, but sometimes, a picture says more than a thousand words. Over the years, I've often talked about how the technology world is iterative, about how products are virtually always built upon that which came before, about how almost always, multiple people independently arrive at the same products since they work within the same constraints of the current state of technology. This elementary aspect of the technology world, which some would rather forget, has been illustrated very, very well in one of Samsung's legal filings against Apple.

Yes and with hindsight the tech battle moved to mobile stuff, but mobile phones were and are a risky business to get in to. In 2007 Nokia and RIM were big players and a load of "others" were in the game too.

Most mobile phone makers aren't doing very well. Had the original iPhone been a bust, it's second generation may not have created enough buzz to make it sell like it did.

If Apple now wants to build television sets I suspect it will be even more difficult to do. Even though phones and televisions kind of share the same price segment people are less likely to replace a working television. I would only do that if it was something I couldn't resist, meaning it would have to be a television+++.
